Looks like Win95 when shuting down and signing in.

When I get ready to shut my computer down, it gives me the old pop up like 95
where you can scroll down to select if you want to shut down, restart or log
out. And when I turn the computer back on it asks for a password that doesnt
exist so if I just select ok, it signs in. The other day I was deleting old
games off the HD and now it's doing this.
